When -W is given we search the lines between the end of the current

we merge those two hunks as they must be part of the same function.

If the next change is an appended chunk we abort the search early in
get_func_line(), however, because its line number is out of range. Fix
that by searching from the end of the pre-image in that case instead.

rev-list: disable bitmaps when "-n" is used with listin... Jeff King Fri, 3 Jun 2016 07:08:05 +0000 (03:08 -0400)

rev-list: disable bitmaps when "-n" is used with listing objects

You can ask rev-list to use bitmaps to speed up an --objects
traversal, which should generally give you your answers much
faster.

Likewise, you can ask rev-list to limit such a traversal
with `-n`, in which case we'll show only a limited set of
commits (and only the tree and commit objects directly
reachable from those commits).

But if you do both together, the results are nonsensical. We
end up limiting any fallback traversal we do to _find_ the
bitmaps, but the actual set of objects we output will be
picked arbitrarily from the union of any bitmaps we do find,
and will involve the objects of many more commits.

It's possible that somebody might want this as a "show me
what you can, but limit the amount of work you do" flag.
But as with the prior commit clamping "--count", the results
are basically non-deterministic; you'll get the values from
some commits between `n` and the total number, and you can't
tell which.

And unlike the `--count` case, we can't easily generate the
"real" value from the bitmap values (you can't just walk
back `-n` commits and subtract out the reachable objects
from the boundary commits; the bitmaps for `X` record its
total reachability, so you don't know which objects are
directly from `X` itself, which from `X^`, and so on).

So let's just fallback to the non-bitmap code path in this
case, so we always give a sane answer.

rev-list: "adjust" results of "--count --use-bitmap... Jeff King Fri, 3 Jun 2016 07:07:34 +0000 (03:07 -0400)

rev-list: "adjust" results of "--count --use-bitmap-index -n"

If you ask rev-list for:

git rev-list --count --use-bitmap-index HEAD

we optimize out the actual traversal and just give you the
number of bits set in the commit bitmap. This is faster,
which is good.

But if you ask to limit the size of the traversal, like:

git rev-list --count --use-bitmap-index -n 100 HEAD

we'll still output the full bitmapped number we found. On
the surface, that might even seem OK. You explicitly asked
to use the bitmap index, and it was cheap to compute the
real answer, so we gave it to you.

But there's something much more complicated going on under
the hood. If we don't have a bitmap directly for HEAD, then
we have to actually traverse backwards, looking for a
bitmapped commit. And _that_ traversal is bounded by our
`-n` count.

This is a good thing, because it bounds the work we have to
do, which is probably what the user wanted by asking for
`-n`. But now it makes the output quite confusing. You might
get many values:

- your `-n` value, if we walked back and never found a
bitmap (or fewer if there weren't that many commits)

- the actual full count, if we found a bitmap root for
every path of our traversal with in the `-n` limit

- any number in between! We might have walked back and
found _some_ bitmaps, but then cut off the traversal
early with some commits not accounted for in the result.

So you cannot even see a value higher than your `-n` and say
"OK, bitmaps kicked in, this must be the real full count".
The only sane thing is for git to just clamp the value to a
maximum of the `-n` value, which means we should output the
exact same results whether bitmaps are in use or not.

The test in t5310 demonstrates this by using `-n 1`.
Without this patch we fail in the full-bitmap case (where we
do not have to traverse at all) but _not_ in the
partial-bitmap case (where we have to walk down to find an
actual bitmap). With this patch, both cases just work.

I didn't implement the crazy in-between case, just because
it's complicated to set up, and is really a subset of the
full-count case, which we do cover.

t2300: run git-sh-setup in an environment that better mimics the real life

When we run scripted Porcelains, "git" potty has set up the $PATH by
prepending $GIT_EXEC_PATH, the path given by "git --exec-path=$there
$cmd", etc. already. Because of this, scripted Porcelains can
dot-source shell script library like git-sh-setup with simple dot
without specifying any path.

t2300 however dot-sources git-sh-setup without adjusting $PATH like
the real "git" potty does. This has not been a problem so far, but
once git-sh-setup wants to rely on the $PATH adjustment, just like
any scripted Porcelains already do, it would become one. It cannot
for example dot-source another shell library without specifying the
full path to it by prefixing $(git --exec-path).

t5500 & t7403: lose bash-ism "local"Junio C Hamano Wed, 1 Jun 2016 20:56:08 +0000 (13:56 -0700)

t5500 & t7403: lose bash-ism "local"

In t5500::check_prot_host_port_path(), diagport is not a variable
used elsewhere and the function is not recursively called so this
can simply lose the "local", which may not be supported by shell
(besides, the function liberally clobbers other variables without
making them "local").

t7403::reset_submodule_urls() overrides the "root" variable used
in the test framework for no good reason; its use is not about
temporarily relocating where the test repositories are created.
This assignment can be made not to clobber the variable by moving
them into the subshells it already uses. Its value is always
$TRASH_DIRECTORY, so we could use it instead there, and this
function that is called only once and its two subshells may not be
necessary (instead, the caller can use "git -C $there config" and
set a value that is derived from $TRASH_DIRECTORY), but this is a
minimum fix that is needed to lose "local".

test-lib: add in-shell "env" replacementJeff King Wed, 1 Jun 2016 07:04:26 +0000 (03:04 -0400)

test-lib: add in-shell "env" replacement

The one-shot environment variable syntax:

FOO=BAR some-program

is unportable when some-program is actually a shell
function, like test_must_fail (on some shells FOO remains
set after the function returns, and on others it does not).

We sometimes get around this by using env, like:

test_must_fail env FOO=BAR some-program

But that only works because test_must_fail's arguments are
themselves a command which can be run. You can't run:

env FOO=BAR test_must_fail some-program

because env does not know about our shell functions. So
there is no equivalent for test_commit, for example, and one
must resort to:

(
FOO=BAR
export FOO
test_commit
)

which is a bit verbose. Let's add a version of "env" that
works _inside_ the shell, by creating a subshell, exporting
variables from its argument list, and running the command.

Its use is demonstrated on a currently-unportable case in
t4014.

"git describe --contains" often made a hard-to-justify choice of
tag to give name to a given commit, because it tried to come up
with a name with smallest number of hops from a tag, causing an old
commit whose close descendant that is recently tagged were not
described with respect to an old tag but with a newer tag. It did
not help that its computation of "hop" count was further tweaked to
penalize being on a side branch of a merge. The logic has been
updated to favor using the tag with the oldest tagger date, which
is a lot easier to explain to the end users: "We describe a commit
in terms of the (chronologically) oldest tag that contains the

rebase -i: remove an unnecessary 'rerere' invocationJohannes Sixt Fri, 27 May 2016 16:28:21 +0000 (18:28 +0200)

rebase -i: remove an unnecessary 'rerere' invocation

Interactive rebase uses 'git cherry-pick' and 'git merge' to replay
commits. Both invoke the 'rerere' machinery when they fail due to merge
conflicts. Note that all code paths with these two commands also invoke
the shell function die_with_patch when the commands fail.

Since commit 629716d2 ("rerere: do use multiple variants") the second
operation of the rerere machinery can be observed by a duplicated
message "Recorded preimage for 'file'". This second operation records
the same preimage as the first one and, hence, only wastes cycles.
Remove the 'git rerere' invocation from die_with_patch.

Shell function die_with_patch can be called after the failure of
"git commit", too, which also calls into the rerere machinery, but it
does so only after a successful commit to record the resolution.
Therefore, it is wrong to call 'git rerere' from die_with_patch after
"git commit" fails.

If lines are added at the end of a file, diff -W shows the whole file.
That's because get_func_line() only considers the pre-image and gives up
if it sees a record index beyond its end.

Consider the post-image as well to see if the added lines already make
up a full function. If it doesn't then search for the previous function
line by starting from the bottom of the pre-image, thereby avoiding to
confuse get_func_line().

Reuse the existing label called "again", as it's exactly where we need
to jump to when we're done handling the pre-context, but rename it to
"post_context_calculation" in order to document its new purpose better.

Documentation: bold literals in man

Backticks are emphasized through monospaced styling in the HTML
version of Git documentation. But they were left unstyled in the
manual pages.

To make the man pages more comfortably read, `MAN_BOLD_LITERAL` was
added by 5121a6d (Documentation: option to render literal text as
bold for manpages, 2009-03-27). It allowed the user to build the
manpages with literals in bold style.

For precaution it was not set by default back then.

Since 79c461d (docs: default to more modern toolset, 2010-11-19), it
is assumed ASCIIDOC 8 and at least docbook-xsl 1.73 are used, so the
need for compatibility concern is much lessor now.

Remove `MAN_BOLD_LITERAL`, and typeset literals as bold by default .
Add `NO_MAN_BOLD_LITERAL`, a new Makefile option, disabling this
feature when defined.

Makefile: move 'ifdef DEVELOPER' after config.mak* inclusion

The DEVELOPER knob was introduced in 658df95 (add DEVELOPER makefile
knob to check for acknowledged warnings, 2016-02-25), and works well
when used as "make DEVELOPER=1", and when the configure script was not
used.

However, the advice given in CodingGuidelines to add DEVELOPER=1 to
config.mak does not: config.mak is included after testing for
DEVELOPER in the Makefile, and at least GNU Make's manual specifies
"Conditional directives are parsed immediately", hence the config.mak
declaration is not visible at the time the conditional is evaluated.

Also, when using the configure script to generate a
config.mak.autogen, the later file contained a "CFLAGS = <flags>"
initialization, which overrode the "CFLAGS += -W..." triggered by
DEVELOPER.

This patch fixes both issues.

Documentation: add instructions to help setup gmail 2FA

For those who use two-factor authentication with gmail, git-send-email
will not work unless it is setup with an app-specific password. The
example for setting up git-send-email for use with gmail will now
include information on generating and storing the app-specific password.

format_commit_message: honor `color=auto` for `%C(auto)`Edward Thomson Fri, 27 May 2016 03:46:10 +0000 (22:46 -0500)

format_commit_message: honor `color=auto` for `%C(auto)`

git-log(1) documents that when specifying the `%C(auto)` format
placeholder will "turn on auto coloring on the next %placeholders
until the color is switched again."

However, when `%C(auto)` is used, the present implementation will turn
colors on unconditionally (even if the color configuration is turned off
for the current context - for example, `--no-color` was specified or the
color is `auto` and the output is not a tty).

Update `format_commit_one` to examine the current context when a format
string of `%C(auto)` is specified, which ensures that we will not
unconditionally write colors. This brings that behavior in line with
the behavior of `%C(auto,<colorname>)`, and allows the user the ability
to specify that color should be displayed only when the output is a
tty.

Additionally, add a test for `%C(auto)` and update the existing tests
for `%C(auto,...)` as they were misidentified as being applicable to
`%C(auto)`.

Tests from Jeff King.
